09.10.2017 These equipment are sold in various capacities from 8 m 3 to over 200 m 3 per hour. Calcium carbide is introduced from the top of the generator shell into the water. The chemical formula of this reaction can be expressed as: CAC2 + 2 H2O → C2H2 + CA (OH)2 This reaction should only be conducted under controlled conditions.

The production of calcium carbide involves two main steps: electrolyzing lime with coke or coal, and then mixing with water. calcium oxide is created by passing carbon dioxide through lime kilns. The resulting slaked lime is then mixed with coke in an electric furnace. The mixture leaves as molecular lime gas, which reacts with atmospheric carbon dioxide to form solid calcium

The equipment used for the smelting of calcium carbide is similar to that employed in electric furnaces used for other forms of ferroalloys processing, where carbon is used as a reductant. Calcium carbide is also an intermediate product in the smelting of calcium–silicon alloy. Technical grade calcium carbide is crystallized from the melt and contains ~80% CaC 2 and

From the examination on the calcium carbide production process plant., we believe that its production process equipment and production process control are standardized and reliable. The by-product of ferrosilicon is mainly produced due to the insufficient purity of raw materials such as limestone, coke and blue carbon. It contains excessive impurities of silica and ferric
